bands of film or of opaque material bearing p1ctures or other matterwhich are reproduced by reflected light, and in the present embodimentthese various features are realized together in one machine.

The invention, in one feature thereof, prevents or eliminates adangerous amount of.

heat in the neighborhood of the film, thereby rendering it entirelypracticable to permit the machine to run on for protracted periods oftime without watching or testing as to the amount of heat evolved, aswould ordinarily be necessary to avoid ignition or explosion ofinflammable film. Other features of the invention, and advantagesflowing therefrom will appear hereinafter or be obvious herefrom.

Referring more particularly to the embodiment illustrated herein by wayof example, a machine is provided with a suitable frame comprising abase or foot plate 1, adapted to rest upon a support, from which .to'ot'plate extends upwardly the apertured frame piece 2, having thehorizontal member 3 extending along the top thereof. This frame may beintegral if desired, and will be of suitable material and construction.In the form shown, if the base be firmly held, the whole machine ismaintained in stable position. s Mounted on a cross piece 4 of the framein bosses 5 and 6 are rods 7 and 8, upon which rods a lamp housing,which may also carry the Whole or a part of the lenses may be detachablymounted. Cooperating with the supports just described, are provided lampand lens housings interchangeable the one with the other, whereby themachine may reflection.

tel-changeable lamp and lens housin are devices for feeding the endlessband oi film or other matterto be illuminated and illus- 'trat'ed,whether by direct rejection or by reflection, although in certainfeatures of the invention other-forms than the endless band may beemployed. Whether a strip or band for projection 'or reflection beemployed, it will be styled herein for convenience a film band.

In the embodied form there are provided along the top frame piece 3 aseries of driven rolls 10, 11,12, 13 and 14, some or all of which engagethe film-band by positive means, as forexample sprocket teeth 15engaging with In cooperative juxtaposition with the insprocket holes inthe film whereby the feed of the film is positive and regular with.respect to the rotation of-the sprocket rolls.

Gotiperating with these rolls are other 'rolls, which need not bedriven, for directing the film band m along its pathway through themachine. Such additional rolls comprise rolls 16, 17 and 18 arrangedalong-the bottom part of the upright frame member 2. A. suitable take-updevice for the slack in the film may be provided, and in the embodiedform this is shown applied to the roller 18, said roller 18 beingjournaled at one end of a lever 19, which lever is pivotally supportedat 20 upon the frame 2. The other end of the lever 19 is acted on by aspring 21, which operates to put the neces-' ,sary tension upon the filmband w.

Means are provided also for preserving or affording a reserve supply'ofthe film band, wherebyqthe quantity and Variety of matter to be shown isgreatly increased without increase in the size of the machine. In theembodied form rollers 22, 23, and 24 are chain 46, said chainpassing'likewise about journaled in a cross piece 25 of the frame 2, thefilm band m running alternately; over one of the top'rollers 10, 11, and12 and thence to one of the bottom rolls 22, 23 and 24, or in likemanner over various successive sets of these rollers, as may bedesirable for the length of film band it iswished to utilize at anyparticular time. Cotiperating also with the rollers 14 and 16. are rolls26 and 27,

supportedin bracket 147, mounted upon the frame 2.

- Means are provided for giving intermittent rotary motion to the drivenfilm carrying rolls to provide the requisite intermittent movement ofthe film withthe intervening dwells while the pictures orother. matterare being shown. In the embodied form of said means a motor 35, of anysuitable kind is provided, and shown asan electric motor, having apulley ,36 upon the shaft. thereof. Over pulley 36 runs a beltv37, saidbelt 37 also running over a pulley 38, which is fixed on ashaft- 39,-said shaft 39 being mounted in bearings 40 and 41=on the machine frame.Fixed on the shaft 39 is ,a worm thread 42 cotiperating with a wormwheel 43 upon the shaft 44. The shaft 44 passes through the'machineframe and on the oppositeside (Fig. 3) this shaft has fixed thereon asprocket wheel 45. Passing over the sprocket wheel 45 is a sprocketsprocket wheels 47, 48, 49 andv52. Sprocket 5 2 is fixed on the shaft ofroller 14. Asuit able take-up device is provided in connec-- tion withthe sprocket .wheel 49, and as shown said sprocket 'wheelis rotatablymounted on an arm 50, which-arm is pivoted at 51 upon the machine frame."The arm 50 is acted upon by a suitable spring, screw or othercompensatingdevice.

In the embodied form of emeans forand 60. The sprocket 57 engages with asprocket chain 61. The sprocket chain 61 engages also each of thesprocket wheels 53, 54, 55 and 56, thus driving the rolls 10, 11, 12,.13 and 14 in unison with the intermittent movement of the sprocket wheel57.

The sprocket wheel 57 is fast to an intermittently moving sprocket wheel87 (which is described later), and wheel 57 thereby imparts intermittentmovement to chain 61 and to rollers 10, 11, 12, 13 and 14, from wheel87. Between .the sprocket wheels 53 and 54 is a sprocket wl1eel 62,which holds ,the sprocket chain 61 in engagement with the lower part ofthe two sprocket wheels 53 and 54. Similar sprocket wheels 63 and 64 areprovided between the sprocket wheels 54, and 55, and 55 and 56,respectively. A suitable slack taking up' device is provided, shownherein as a sprocket wheel 65, which wheel is mounted upon a lever 66,said lever bein pivoted at 67 upon the machine frame. T e other arm oflever 66 is acted on by a spring 68.

The embodied form of means for effecting the intermittent movement ofthe driven rollers 10, 11, 12, 13 and 14 from the chain 46, issubstantially the same as that shown in application for patent, Ser.,No. 859,275, of Dumars and Darby filed August 31, 1914.

Briefly described, the bracket 58'is extended downwardly to furnish abearing for a slotted rotary disk or star wheel 80 provided withradiallyarranged slots 81. Upon the chain 46 is a pin 82 projectingfromthe chain 46 into the path of the star wheel or rotatable diskv 80, andadapted each time it passes the disk to enter one of the slots 81 andimpart thereby to the disk 80 a quarter rotation- The disk 80 remains atA rest thereafter until'the pin 82 again en gages with the next slot 81of the wheel 80. Thechain 46 and pin 82 are guided in their travel pastthe wheel 80 by guides 83' and 84 fastened upon the machine frame.

Fixed to rotate with the wheel 80 is -a double sprocket wheel.85, overwhich runs a sprocket chain 86, said sprocket chain running over thesprocket wheel 87 fixed on the shaft 88 of the roller 14. Sprocket wheel87 is fixed to rotate with sprocket 57,'

the sprocket chain 61 running over wheel 57, and thereby the sameintermittent mo-'- tion is imparted to each of the driven rolls tion bysprings 107 and 108. Pivotally con- 11, 12, 13' and 14. Running alsoover the wheel 91 fixed on the shaft 92 of the roller 16. Roll 16 isthereby also positively driven unison with the other feeding rolls, andthere is a uniform and exact feeding of the film band past the light.The rolls 16 may also be provided with sprocket teeth 93. A

centering disk 98 and coiiperating stop 99' may be employed, and asshown are gen- I erally similar in construction to those shown inapplication Ser. No. 859,275. This device operates to accurately centeror frame the film or other pictures. p 1

Means are provided for stopping the action of the light during themovement of the :film band, and according to one feature of held byfastenings 101 and 102 working, re-

spectively, in slots 103 and 104 in the plate 100. The upper end of theplate 100 is of enlarged or T-shape, and has at either end thereof twoinclined cam surfaces 105 and 106 with a level surface 'therebetween.The plate 100 is held resiliently in upper posi- 1' nected to thesliding plate 100 is a link 109,

said link being also pivotally connected to one end of a lever 110,which lever is pivoted upon the frame 111. Pivotally connected to theother end of the lever 111 is a link 112, which link is also pivoted toone end of a switch lever 113. The lever 113-is pivoted at 114 on themachine frame. The terminals 115 and 116 of the light circuit 117 and118 are in position to be opened or closed by the switch 113 as it ismoved from one position to the other with the movement of the plate 112.When the pin 82 approaches the slot 81 in disk 80 just prior to theshifting of the film, the pin encounters the cam surface 105 upon thesliding plate 100, and the plate 100" is, thereby moved downwardlyagainst the pull of itssprings 107 and 108, thereby throwing the switchlever 113- into the open position, as shown in Fig. 3. When the fgin 82leaves the slot 81, at the close of the m shifting movement, it. passesout of contact with the surface 106, and the plate 100 slides upwardlyunder the pull of the springs thereby automatically shifting the lever113 and turning on the light. Light wires 119 are shownextending fromthe circuit 118 up into the lamp house. A hand switch 120 may-beprovided for turning on and off the light. 7

Referring nowto the ineans for projecting the lightthrough the film, andin connection therewith the embodied form of means for of the film, inthe embodied form a lamp house 125 is detachably mounted on the rods 7and 8, which rods may be slid in and out of their bearings in the frame.The lamp house 125 is carried upon a frame 126 and upon a frame 127 ateither end thereof, said frames having apertures within which are therods 7 and '8, the frames 126 and 127 being longitudinally adjustablealong the rods, and the lamp house being mounted into place and removedtherefrom by longitudinally withdrawing the rods. The lamp house 125 isprovided with a lamp 128, the light from which is suitably directed andprojected through the film. A suitable reflector 124 is provided, andalso a door 123.

As embodied the means for cooling the light are mounted within the lamphouse. In the embodied form, a mirror or other suitable reflectingsurface 130 is mounted to receive the concentrated or focused rays fromthe lens 129. The light rays are reflected from the surface 130 throughthe condensing lenses 131, through the film 0c, and through theprojecting lens 132. In the embodied form, the mirror or reflectingsurface 130 has formed at the back thereof a chamber 134, in which acooling medium may be inclosed or may be circulated therethrough, suchas a body or stream of air or water. Said chamber may consist of amaterial having great conductivity, such as copper, and may be arrangedto have a constant fluid circulation therethrough, as of air or water.The projecting lens 132 may be demountable in view of the adaptabilityof the machine for the projection of light through a film band or thereflection of the light therefrom. As embodied, the projecting lens 132v is carried upon a stem 135, which stem is mounted in a bracket 136.Bracket 136 is fixed upon the machine frame, and is provided with aclamping screw 137 for holding the lens in proper position.

Means are provided for holding the film flat and true during theprojection of the picture, and the embodied form thereof issubstantially. the same as that shown in pending application Ser. No.859,275 hereinabove referred to. In such embodiment, transparent plates140 and 141 of glass or other suitable material are arranged uponopposite sides of the film band a; at the place of projection. Theplates 140'and 141 are relatively movable toward and from each stritherebetween and to release it from its fee or travel. As embodied theplate is stationary, and is mounted in the front of the lamp house,andplate 141 is movable. The plate 141 is mounted upon four rods 142,which rods are reciprocably mounted in apertures in cross pieces 143 and144 for the .up" er, rods, and 145 and 146 for the lower ro 's,sai dcross pieces being carried upon the bracket 147 in which the feedingrolls 26 and 27 are mounted, said bracket being car-- ried upon themachine frame. The plate 141is impelled toward the film by springs 148coiled about the pins 142. The pins 142 are retracted against theirsprings by arms 14.9 and 150, mounted respectively on shafts 151 and 152herein. Said shafts 151 and 152 are rocked by an arm 153, which .ismounted in frame 2, and which engages with a lug 154 upon the slidingplate 100. The plate 141 is-thus drawn away from pressure against thefilm during the feeding thereof. Referring now to the adaptation of thedevice for reflection work, the lamp house 125 and its lenses arequickly and readily removed from apparatus substituted therefon. Thelamp house 165, adapted for reflection work, may be mounted upon themachine or removed therefrom in the same manner as the lamp house 125.Lamp house 165 is carried on a frame 166, likewise adjustably anddetachably and 8. When the device is used for reflection work the filmband -or similar band is preferably not run over the front rollers 14and 16, but is run downwardly from the roller 13 to the roller 17 ,asshown in Fig. 2. At the back of the lamp house. 165 is preferably a door167 within which the film band :1; passes downwardly. Suitable pressuremay be put upon the film band,'and for this purpose a plate 168, havingits ends curved away-from the film band is mounted upon the lamp house165. A similar having reflectors .182 and spring pressed plate 169ismounted upon the doorway 167 and is held against the film band a: byresilient pressure. The plate 169 is mounted upon four rods 170, whichare reciprocably carried in apertures in the door 167 and in aperturesin a spider 171 carried upon a bolt or other support 172 fixed to thedoor 167 Suitable springs are provided for urging the plate 169 withresilient action and with the requisitedegree of pressure against thefilmband m.

The illumination which is projected upon the face of the film band isprovided, as embodied,by lights 180 and 181 arranged within the lamphouse 165 at 183, which pro-- ject the light upon the surface of thefilm as within the lamp house. The light is then reflected outwardlythrough projecting lens From all the foregoing. it will be understoodthat a machine has been provided realizing the objects of invention andadvanthe machine, and the reflection mounted upon the supporting rods 7either side, and

'ranged in pairs to direct the pared with the machine itself, which isof relatively small bulk, thereby providing a great variety ofsubjectmatter without changing film bands, thereby greatly enhancing theefficiency of the device both for advertising and for amusementpurposes. The device is self-regulating and self-controlling in anunusual degree, as the film band always feeds in one direction, andavoids rewinding thereof, and reversal of the motor or other mechanism,and obviates all danger of the pictures getting out of register. guardedagainst over-heating and all danger of fire is eliminated, even with theordinary inflammable film, thereby, obviating observation to avoidoverheating.

The invention in its broader aspects is not limited to the precisemechanism shown and described, but changes may be made therein withinthe scope of the appended chaims without departing from the principlesof the invention and without sacrificing its chief advantages.
